Flux helps just with one part. Relax in evening due to removal of blue light. But second part is, that in morning and during day, you really should see blue/full spectrum and intensive light. Either by going outside, or you can buy some light therapy lamp that provides you with this (when natural light is impossible). I do not think it's good idea to deprive yourself of blue light whole day.

Not to rain on your parade but get a colorimeter and check your screen I’ve used my xrite i1 pro and the amount of blue light doesn’t actually change that much when you switch your white point temperature to warmer settings and especially when it’s as high as 5500K.
